Summary of my sermon, based on Luke 15:1-10. Preached at Greenhills Christian Fellowship Toronto on March 8, 2026.
Today, we are looking at Luke 15, which contains some of the best-known teachings of Jesus, including the parable of the prodigal son. However, before getting to that famous story, Jesus tells two shorter parables that perfectly set the stage: the parable of the lost sheep and the parable of the lost coin. These two parables provide essential insights into evangelism and what it truly means to seek the lost. To understand them, we first have to understand the situation that prompted Jesus to tell them.
Luke tells us that tax collectors and sinners were drawing near to Jesus, and the Pharisees and scribes grumbled, saying that He receives sinners and eats with them. Jesus was speaking directly against the religious leaders of His day who were ignoring and ostracizing entire groups of people. Tax collectors were despised as corrupt traitors who extorted their fellow Jews on behalf of the Roman Empire. The group labeled “sinners” included those living in overt moral failure, but it also included people who were ritually impure due to sickness or disability. Instead of helping these marginalized people find restoration through the grace of God, the Pharisees acted as gatekeepers, completely shunning them.
Unfortunately, this holier-than-thou attitude can still be found in some churches today. There is sometimes a bias that assumes people who look, dress, or speak differently do not belong. But Jesus made His mission clear: it is the sick who need a physician, not the healthy. A church must be a place of healing for those on the margins of society. I remember ministering to a homeless man in Fort McMurray who used to sleep inside bank ATM vestibules to survive the brutal winter. When he came to our church, he clearly did not fit the mold of a typical youth group member, but we welcomed him, ministered to him, and shared the gospel with him. While we must maintain a robust, correct theology, we must never become an exclusive social club that loses its heart for the lost.
Jesus illustrates the effort required to reach the lost through His parables. He describes a shepherd who leaves his ninety-nine sheep in the open country to go after the one that is missing, not knowing how far he will have to travel. He also describes a woman who loses a single coin in her home, lighting a lamp and diligently sweeping the house until she finds it. Both stories emphasize the immense effort and distance we must be willing to cover to seek out lost souls.
Today, that distance is rarely physical. With the world coming to our cities, the distance we must bridge is often one of worldview and culture. Sharing the gospel effectively requires us to understand how different people perceive sin and salvation. In a guilt-based society, like the classical West, sin is breaking a moral law, and Jesus pays our legal debt. In an honor-based culture, which represents much of the world, sin is public shame and broken relationship, and Jesus takes our shame to restore us to honor. In a fear-based society, sin is enslavement to dark forces, and Jesus conquers the powers of darkness to set us free. The gospel never changes, but we must put in the hard work of contextualizing it so people can truly understand their need for grace.
When the shepherd finds his sheep and the woman finds her coin, they immediately call their friends and neighbors to rejoice. Jesus tells us that, in the exact same way, there is immense joy before the angels of God over one single sinner who repents. To the world, one sheep or one coin might not seem incredibly valuable, but to God, every lost soul is a profound treasure. As believers, we must dedicate our lives and our churches to seeking out that treasure, putting in the diligent effort to bridge the gap and share the restorative love of Christ with everyone around us.
